FUEL-MAGAZINE FOR STEAM-GENERATORS.

EPECEFICATIGN forming part of Letters Patent No. 319,005, dated June1835- Application filed March .27, 1885. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE Manama, a citizen of the United States, and aresident of Chicago, county of Cook, and State of Illinois, haveinvented new and useful Improvements in Fuel-Magazines forSteanrGenerators, of which the following is a specification, rcferencebeing bad to the accompanying drawings, illustrating the invention inwhich like letters indicate like parts in the different figures.

The purpose of this invention is to simplify the construction andfacilitate the working of a two-part or telescopic fuel-magazineemployed in the fire-boxes of steanrgenerators, whereby the fines of thegenerator can be exposed for cleaning. The working of a twopartfuel-magazine over the grates of a firebox has been attended wit-h twodifficulties. The one is the escaping gas when the lower section isbeing raised, and the other is the destruction of the raising mechanismby the heat. I have overcome these difficulties by suspending the lowersection by rods which pass through a ring on the top of the uppersection, the same rods also being employed to elevate the said lowersection by means of loops or handles formed on their upper ends for thatpurpose. By this construction no gas can escape during the manipulationof the lower section, and no part can become fouled or get out ofworking order. As to the he cessity of the device, it is observed bycareful experiment that the screws, pulleys, and cords which areemployed to telescope magazines located outside of the firebox becomewholly inoperative when placed inside of the fire-box in consequence ofthe intense heat.

Figure l is a vertical longitudinal section of the front portion of asteam-generating furnace and a sectional elevation of my inventioncombined therewith; Fig. 2, an elevation of the lower section of themagazine, a sectional elevation of the upper section thereof, and atransverse sectional elevation of the steamgenerator; Fig. 3, a top viewof the magazine removed from the furnace.

G represents the firebox, I the grate-bars, H the crown-sheet, F thewagon-top, K the furnace-door, and J the boiler, of a well-known modernsteam-generator.

B represents the cylindrical upper section of the magazine, which at itsends is attached to the crown-sheet H and the wagon-top F, and on thetop of this section is removably attached a ring, E, on which the lid 0to the magazine is placed.

A represents the lower section of the magazine, which is constructedwith reference to the stationary part B, so as to be telescoped orraised up into it. This is done by means of rods or chains a a, attachedto the top of the lower section, and extending through the ring E, andabove the ring E are provided with loop-handles D D, which by hearing onthe ring E sustain the weight of the section A and furnish means forlifting out the said section by hand and uncovering the boilerflues J.

The section A is fitted loosely in the stationary part B; but is largeenough to prevent coal from passing down between them. The material usedfor the magazine is cast-iron. The form shown is cylindrical; but otherforms may be employed.

Having thus described my invention, what- I claim, and desire to secureby Letters Patent,

In telescopic fuel-magazines, the upper stationary section, 13, attachedto the crownsheet H and wagon-top F and placed over the grates of thefire-box, in combination with the lower section, A, and ring E, and alsowith the rods a a, which are attached to the said section A,extendthrough the ring E, and are provided with loop-handles D D at their topends for suspending the lower section from the ring and elevating it, asand for the purpose specified.
